The `\nabla` command is valid only in math mode.
It generates a miscellaneous symbol:
`<mi>∇</mi>` (Unicode U+2207, ∇).
See description of the
`\ldots` command.

Instead of `\expandafter\def\csname xxx\endcsname ...`
you can say `\@namedef{xxx}...`. The result is the same.

Instead of `\csname xxx\endcsname`
you can say `\@nameuse{xxx}`. For instance, if you have two
counters A and B, and you want that A prints in the same way as B,
more precisely, you want `\theA` to call `\theB`,
you say `\Test{A}{B}`, after the following definition:
`\def\Test#1#2{\global \@namedef {the#1}{\@nameuse {the#2}}}`.

The `\natural` command is valid in math mode and text mode.
It generates a miscellaneous symbol:
`<mo>♮</mo>` (Unicode U+266E, ♮).
See description of the
`\qquad` and
`\ldots` commands.

The `\ncong` command is valid only in math mode.
It generates:
`<mo>&2247;</mo>`, ≇.

The `\ne` command is valid only in math mode.
It generates a relation symbol:
`<mo>≠</mo>` (Unicode U+2260, ≠).
See description of the `\le` command.

The `\nearrow` command is valid only in math mode.
It generates an arrow that points North-East:
`<mo>↗</mo>` (Unicode U+2197, ↗).
See description of the `\leftarrow` command.

A typical class file contains a declaration like
`\NeedsTeXFormat{LaTeX2e}[1995/12/01]`. This is ignored by
*Tralics*.

The `\neg` command is valid only in math mode.
It generates a miscellaneous symbol
(character ¬).

See description of the
`\ldots` command.

The `\neq` command is valid only in math mode. It is the same as `\ne`.
It generates a relation symbol:
`<mo>≠</mo>` (Unicode U+2260, ≠).
See description of the `\le` command.

This command expands to `\hskip .11em plus.33em minus.07em`.

You can say `\newboolean{foo}`, this is the same
as `\newif\iffoo`. However, an error is signaled
if `\iffoo` already
exists. The control sequence `\iffoo`
is created by `\csname`, nasty
errors may occur. The boolean value of foo can be changed by
`setboolean{foo}` (rather than by `\footrue`
or `\foofalse`). It can be tested via `\boolean`.

(see description of `\ifthenelse`)
(also see `\newif`) for some
details).

Example (translation is ``oka okb`')

```
{ %The command \bad is not executed here
\def\double#1{#1#1}
\newboolean{f\double o}
\def\swap{\setboolean{f\double o}{\iffoo fals \else TRU\fi e}}
\ifthenelse{\boolean{foo}}{\bad}{oka}
\swap
\ifthenelse{\boolean{foo}}{okb}{\bad}
}
```

The `\newbox` command is similar in principle to
`\newcount`.
After `\newbox\foo`, the `\foo` commands
refers to some box, and each call to `\newbox` produces a
reference to a different box. You say `\setbox\foo = \hbox{...}`
if you want to put something in the box, `\box\foo` or
`\copy\foo` if you want to use the box or its copy.
Note: `\foo` is, in reality, a reference to a character.
(Lamport calls it a `bin').

The `\newcolumntype` command can be used to define a new column
type (in addition to flush left, flush right and center).

See documentation
on *arrays*.

The LaTeX way of defining commands is via
`\newcommand`. Here are some examples

\newcommand\NCA{nca} \newcommand{\NCB}[0]{ncb} \newcommand{\NCC}[2]{ncc#1#2} \newcommand{\NCD}[2][x]{ncd#1#2} \NCA and \NCB and \NCC{arg1}{arg2} and \NCD[arg1]{arg2} and \NCD{arg2}

The argument of `\newcommand` should be a single token
(`\cmd25` is wrong), a command name (or an active character)
that is undefined. It is followed by the number of arguments (in brackets,
default is zero, only explicit digits are allowed), followed by an optional
argument in brackets, followed by a command body. In the body, `#1`
refers to the first argument, `#2` to the second, etc (you cannot
use `#7` if the command does not take at least seven arguments).

In the case of a command like `\NCD`, the number of arguments
should be at least one. When you say `\NCC{y}`, then `y`
is the second argument (and the first argument takes its default value, here `x`).
When you say `\NCD[1]{2}`, the first argument is `1`,
the second argument is `2`. You can put an optional `*`
after `\newcommand`, it was ignored by previous versions of *Tralics* (it means
non-`\long` in LaTeX).

This command allocates a new counter register and defines a macro that references it.

There are N=256 count registers, indexed by a number between 0 and N-1,
for instance `\count0`, or `\count23`.
(In current versions of *Tralics*, N is 1024).
It is sometimes wise to give a symbolic name to
a counter. For instance, `\countdef\foo 25` makes `\foo`
a reference to `\count25`. On the other hand, it is more efficient
to say `\foo` than `\count25`, (because
it avoids a call to *scanint*)
and `\foo3` is not the same as `\count253`.

There is a mechanism that makes sure that a register is not used
more than once: the `\newcount` command uses
a different number each time, first 20, then 21, then 22, etc.
Numbers less than 10 are not allocated. Numbers bewteen 10 and 19 are used by
the new-something mechanism.
When you say
`\newcount\foo`, a counter is allocated, and `\foo`
is made a reference to it. Then `\foo=3` puts 3 in the counter,
`\advance\foo by 1` increments the counter, and
`\the\foo` typesets the counter.
Allocation is always global.

See `\loop` for an example.

The `\newcounter` command is similar in principle to
`\newcount`.
However, LaTeX adds additional features.
When you say `\newcounter\foo`, a number is allocated, say 25,
and the command `\c@foo` is made equivalent to
`\count25`. See for instance
*description of counters*.
The expression `\value{foo}` expands to `\c@foo`,
hence to `\count25`. This means that `\value{foo}=12`
is one way to set the value to 12, but you should say
`\setcounter{foo}{12}`. This sets the value to 12, globally.
You can also say `\addtocounter{foo}{25}`, if you want to
add (globally) 25 to the value of the counter.

You can say `\number\value{foo}` if you want to typeset
the number, and even `\the\value{foo}`. If fact,
you say `\arabic{foo}` if you want an arabic version
(you can use `\roman`, `\alph` etc).
You say `\thefoo` when you want to typeset the counter
foo and what is related (default value is arabic, but you can say
`\renewcommand \thefoo {\roman{foo}}`). You can say:
`\renewcommand \thesection {\thechapter .\arabic{section}}`.
Then `\thesection` typesets `\thechapter`, a dot,
and the section counter as an arabic number.

When you say `\newcounter {section}[chapter]`,
this modifies a property of the chapter counter
(in fact the `\cl@chapter` command), so that, whenever
it is incremented by `\stepcounter`, the section counter is
reset to zero. Example

{ \newcounter{toto} \newcounter{titi}[toto] \newcounter{tata}[titi] \newcounter{tutu}[toto] \setcounter{toto}{10} \setcounter{titi}{20} \setcounter{tata}{30} \setcounter{tutu}{40} \expandafter\show\value{toto}\expandafter\showthe\value{toto} \expandafter\show\value{titi}\expandafter\showthe\value{titi} \expandafter\show\value{tata}\expandafter\showthe\value{tata} \expandafter\show\value{tutu}\expandafter\showthe\value{tutu} \stepcounter{toto} % kills titi, tutu \stepcounter{tata}\thetata=31, \stepcounter{titi}\thetata=0 % titi=1 \stepcounter{tutu} \thetoto\thetiti\thetata\thetutu=11101 \makeatletter \show\cl@toto \show\cl@titi \show\cl@tata \show\cl@tutu }%

Translation is: 31=31, 0=0 11101=11101. *Tralics* prints the following.
Note that `\c@toto` is a pointer into an internal table
that contains catcodes, lccodes, etc.
In some version of Tralics, `\show\c@toto` gives
`\countref1536`, because the counter is at position 1536 if the
integer part of eqtb tabe; in the current version, the result is more precise.

\c@toto=\count26. \show: 10 \c@titi=\count27. \show: 20 \c@tata=\count28. \show: 30 \c@tutu=\count29. \show: 40 \cl@toto=macro: ->\@elt {titi}\@elt {tutu}. \cl@titi=macro: ->\@elt {tata}. \cl@tata=macro: ->. \cl@tutu=macro: ->.

The `\newdimen` command is similar in principle to
`\newcount`.
When you say `\newdimen\foo`, then `\foo` is a
reference to one of the N dimension registers. You can use
`\foo` in the same way as `\dimen0`. For instance
`\foo=25pt` will set the dimension to 25pt.
It is the same as `\setlength{\foo}{25pt}`. You can say
`\advance\foo by 3pt` if you want to increase the value,
or you can say `\addtolength{\foo}{3pt}`.

In TeX N=256, in the current version of *Tralics* it is 1024.

An environment, like `foo` is defined by two commands
`\foo` and `\endfoo`. It is defined by the
`\newenvironment` command, that takes as argument a name
(*Tralics* accepts only characters);
the command associated to this name should not be already defined.

For instance, `\newenvironment{foo} {xxx} {yyy}` is like
`\newcommand{\foo}{xxx}`, `\def\endfoo{yyy}`.
Said otherwise, the `\foo` command can take some arguments,
it can take an optional argument, but `\endfoo` takes no argument
(in the case of `DDD`, we put the argument in an auxiliary command,
that will be used at the end of the environment). Example

```
\newenvironment{AAA}{1\begin{BBB}5}{8\end{BBB}c}
\newenvironment{BBB}{2\begin{CCC}4}{9\end{CCC}b}
\newenvironment{CCC}{3}{a}
\newenvironment{DDD}[2]{#2#1\def\foo{#1}}{\foo}
\newenvironment{EEE}[2][e]{#2#1\def\foo{#1}}{\foo}
%latex code translation
\begin{AAA}67\end{AAA} 123456789abc
\begin{DDD}678\end{DDD} 7686
\begin{EEE}[6]78\end{EEE} 7686
\begin{EEE}78\end{EEE} 7e8e
```

This command is a wrapper around
`\font` in that the expansion of
`\newfont\foo{cmt at 12pt}`
is `\font\foo=cmt at 12pt\relax`.

After `\newif\iffoo`, the two commands `\footrue`
and `\foofalse` are defined: the result of these commands
is to change the meaning of `\iffoo` to `\iftrue` and
`\iffalse` respectively. Moreover, `\iffoo`
is let equal to `\iffalse` initially.

See `\loop` for an example. Note that *Tralics*
wants a name with at least 3 characters.

This is how the macro is defined in plain TeX (why does the TeXbook mention `\edef' ?)

\outer\def\newif#1{\count@\escapechar \escapechar\m@ne \expandafter\expandafter\expandafter \def\@if#1{true}{\let#1=\iftrue}% \expandafter\expandafter\expandafter \def\@if#1{false}{\let#1=\iffalse}% \@if#1{false}\escapechar\count@} % the condition starts out false \def\@if#1#2{\csname\expandafter\if@\string#1#2\endcsname} {\uccode`1=`i \uccode`2=`f \uppercase{\gdef\if@12{}}} % `if' is required

This is how the macro is defined in LaTeX:

\def\newif#1{% \count@\escapechar \escapechar\m@ne \let#1\iffalse \@if#1\iftrue \@if#1\iffalse \escapechar\count@} \def\@if#1#2{% \expandafter\def\csname\expandafter\@gobbletwo\string#1% \expandafter\@gobbletwo\string#2\endcsname {\let#1#2}}

These commands allow you to use more than one index, see \index.

The `\newlanguage` command
is similar in principle to
`\newcount`, but it
allocates a language number (starting with 11). This is currently unused
by *Tralics* that knows only English French and German with numbers 0, 1
and 2.

The `\newlength` command (and its synonym `\newskip`)
is similar in principle to `\newcount`, but it
allocates a skip register.

When you say `\newlength\foo`, then `\foo` is a
reference to one of the N skip registers. You can use
`\foo` in the same way as `\skip0`. For instance
`\foo=25pt plus 2pt` will set the dimension to 25pt plus 2pt.
It is the same as `\setlength{\foo}{25pt}`. You can say
`\advance\foo by 3pt plus 4pt` if you want to increase the value,
or you can say `\addtolength{\foo}{3pt plus 4pt}`.
Note: the commands `\setlength` and `\addtolength`
use as first argument a dimen register or a skip register (more generally,
anything that can be preceded by `\advance\`, for instance
`\parindent`), the second argument will be automatically
converted (by adding zero shrink and stretch, or by ignoring the shrink and
stretch components).

(see also `\newcount`)

In TeX N=256, in the current version of *Tralics* it is 1024.

The `\newline` command is like `\\`, without optional
argument. It does not work inside an array.
See \\.

The `\newlinechar` command can be used to change the value of
the character that TeX uses for a new line.
Not implemented in *Tralics*.

(See *scanint* for details of argument scanning).

The `\newmuskip` command is similar in principle to
`\newcount`, but it allocates
a muskip register.

Translation of `\newpage` is `<newpage/>`.

The `\newread` command is similar in principle to
`\newcount`, but it allocates
an input stream (first number allocated is 1, last one is 15).

The `\newsavebox` command is similar to
`\newbox`
(in the current version, *Tralics* does not check that the
command is undefined).

The `\newskip` command is similar in principle to
`\newcount`, but it allocates a skip register.
It is the same as `\newlength`.

You can say `\newtheorem {X}{Y}`
or `\newtheorem {X}[Z}{Y}`
or `\newtheorem {X}{Y}[T}`. This defines an environment X,
labeled Y. In the second case, it uses the counter Z, otherwise
it uses X as counter. In the last case, the counter is reset whenever T changes
and the value of T is prepended to the value of X.

There is a command `\theoremstyle` that takes
an argument, and remembers it; each theorem can see the value
that was active at the definition.
In the first case shown below, and in the
preview, this value is ignored.

There is a command `\theorembodyfont` that takes
an argument, and remembers it; each theorem uses this value as font for the
body.

There is a command `\theoremheaderfont` that takes
an argument, and remembers it; each theorem uses this value as font for the
body. For some strange reason, this quantity is global (should be used
only once).
Example.

\theorembodyfont{\sl} \theoremstyle{break} \newtheorem{Cor}{Corollary} \theoremstyle{plain} \setcounter{section}{17} \newtheorem{Exa}{Example}[section] {\theorembodyfont{\rmfamily}\newtheorem{Rem}{Remark}} \theoremstyle{marginbreak} \newtheorem{Lem}[Cor]{lemma} \theoremstyle{change} \theorembodyfont{\small\itshape} \newtheorem{Def}[Cor]{Definition} \theoremheaderfont{\scshape} \def\Lenv#1{\texttt{#1}} \begin{Cor} This is a sentence typeset in the theorem environment \Lenv{Cor}. \end{Cor} \begin{Exa} This is a sentence typeset in the theorem environment \Lenv{Exa}. \end{Exa} \begin{Rem} This is a sentence typeset in the theorem environment \Lenv{Rem}. \end{Rem} \begin{Lem}[Ben User] This is a sentence typeset in the theorem environment \Lenv{Lem}. \end{Lem} \begin{Def}[Very Impressive definition] This is a sentence typeset in the theorem environment \Lenv{Def}. \end{Def}

The translation is the following.

<p id-text='1' id='uid1'> <hi rend='sc'>Corollary 1 </hi> <hi rend='slanted'>This is a sentence typeset in the theorem environment </hi> <hi rend='slanted'><hi rend='tt'>Cor</hi></hi><hi rend='slanted'>.</hi> </p> <p id-text='17.1' id='uid2'> <hi rend='sc'>Example 17.1 </hi> <hi rend='slanted'>This is a sentence typeset in the theorem environment </hi> <hi rend='slanted'><hi rend='tt'>Exa</hi></hi> <hi rend='slanted'>.</hi> </p> <p id-text='1' id='uid3'> <hi rend='sc'>Remark 1 </hi> This is a sentence typeset in the theorem environment <hi rend='tt'>Rem</hi>. </p> <p id-text='2' id='uid4'> <hi rend='sc'>lemma 2 (Ben User) </hi> <hi rend='slanted'> This is a sentence typeset in the theorem environment </hi> <hi rend='slanted'><hi rend='tt'>Lem</hi></hi> <hi rend='slanted'>.</hi> </p> <p id-text='3' id='uid5'> <hi rend='sc'>Definition 3 (Very Impressive definition) </hi> <hi rend='small1'></hi> <hi rend='small1'> <hi rend='it'> theorem} This is a sentence typeset in the theorem environment </hi> </hi> <hi rend='small1'><hi rend='it'><hi rend='tt'>Def</hi></hi></hi> <hi rend='small1'><hi rend='it'>.</hi></hi> </p>

The preview is the following

Note that the theorem counter is incremented via a call
to `\refstepcounter`, in fact to `\stepcounter`
plus the internal code that defines a label. In this case, the label
is put on an anonymous XML element, then copied to the `<p>` element.
If the configuration file contains
` xml_xtheorem_name = "dummy"`,
then the name will be `dummy', and the result of the translation will be

<dummy id-text='1' id='uid3'> <p> <hi Rend='sc'>Remark 1 </hi> This is a sentence typeset in the theorem environment <hi Rend='tt'>Rem</hi>. </p> </dummy>

If the configuration file contains
`xml_theorem_name = "theorem"`,
then the name will be `theorem', and the translation is a bit different, as
you can see.

<theorem style='break' type='Cor' id-text='1' id='uid1'> <head>Corollary</head> <p>This is a sentence typeset in the theorem environment <hi Rend='tt'>Cor</hi>. </p> </theorem> <theorem style='plain' type='Exa' id-text='17.1' id='uid2'> <head>Example</head> <p>This is a sentence typeset in the theorem environment <hi Rend='tt'>Exa</hi>. </p> </theorem> <theorem style='plain' type='Rem' id-text='1' id='uid3'> <head>Remark</head> <p>This is a sentence typeset in the theorem environment <hi Rend='tt'>Rem</hi>. </p> </theorem> <theorem style='marginbreak' type='Lem' id-text='2' id='uid4'> <head>lemma</head> <alt_head>Ben User</alt_head> <p>This is a sentence typeset in the theorem environment <hi Rend='tt'>Lem</hi>. </p> </theorem> <theorem style='change' type='Def' id-text='3' id='uid5'> <head>Definition</head> <alt_head>Very Impressive definition</alt_head> <p>This is a sentence typeset in the theorem environment <hi Rend='tt'>Def</hi>. </p> </theorem>

The `\newtoks` command is similar in principle to
`\newcount`, but it allocates a token register.
Assuming that the first allocated register is 11, the following code
makes `\foo` equivalent to `\Bar`. The translation is `123 456'.

\toksdef\foo 11 \newtoks\Bar \foo={123 456} \the\Bar

The `\newread` command is similar in principle to
`\newcount`, but it allocates
a output stream (first number allocated is 1, last one is 15).

The `\nexists` command is valid only in math mode.
It generates:
`<mo>∄</mo>`
(Unicode U+2204, ∄).

This translates to `ŋ` or
(Unicode U+14B, ŋ).
For more info see the
*extended latin characters*.

This translates to `Ŋ`
(Unicode U+14A, Ŋ).
For more info see the
*extended latin characters*.

The `\ngeq` command is valid only in math mode.
It generates:
`<mo>≱</mo>`
(Unicode U+2271, ≱).

The `\ngtr` command is valid only in math mode.
It generates:
`<mo>≯</mo>`
(Unicode U+226F, ≯).

The `\ni` command is valid only in math mode.
It generates:
`<mo>∋</mo>`
(Unicode U+220B, ∋).

The `\niplus` command is valid only in math mode.
It generates:
`<mo>&niplus;</mo>`
(Unicode U+2A2E, ⨮).

The `\nleftarrow` command is valid only in math mode.
It generates:
`<mo>↚</mo>`
(Unicode U+219A, ↚).

The `\nLeftarrow` command is valid only in math mode.
It generates
`<mo>⇍</mo>` (Unicode U+21CD,
⇍).

The `\nleftrightarrow` command is valid only in math mode.
It generates:
`<mo>↮</mo>`
(Unicode U+21AE, ↮).

The `\nLeftrightarrow` command is valid only in math mode.
It generates
`<mo>⇎</mo>` (Unicode
U+21CE, ⇎).

The `\nleq` command is valid only in math mode.
It generates:
`<mo>≰</mo>`
(Unicode U+2270, ≰).

The `\nless` command is valid only in math mode.
It generates:
`<mo>≮</mo>`
(Unicode U+226E, ≮).

The `\nmid` command is valid only in math mode.
It generates:
`<mo>∤</mo>`
(Unicode U+2224, ∤).

The `\noalign` command can be used to insert material between
rows in a table. For instance, in LaTeX, the `\hline` command
is defined to be `\noalign{\hrule height \arrayrulewidth}`,
with a special hack that allows double rules.

In *Tralics*, the only inter-row material allowed is a single
`\hline`. The `\noalign` command is not yet implemented.

The `\noboundary` command inhibits adding an invisible boundary
character. This is used by TeX when computing ligatures and kerns. These
quantities depend on the current font. Since *Tralics* does not
read font information, the `\noboundary` is useless. It fact,
the command provokes an error.

This commands is currently ignored.

The `\nobreakspace` command is identical to `~`, but
cannot be used in math mode.
It generates a non-break space
` ` or ` `.
For more info see the
*latin supplement characters*.

Switches to the default mode, that is not centering, nor flush left, not
flush right, nor quotation.
(see also `\centering`)

This commands behaves like `\cite`, but translation is empty
(see also `\cite`).

You say `\node{x}{y}` for creating a node named x with value y
in a tree.
See `\abarnodeconnect`
for syntax and example.

You say `\nodebox{x}` if you want to put a box around node x.
See `\abarnodeconnect`
for syntax and example.

You say `\nodebox[3pt]{x}` if you want to put a circle around
node x.
See `\abarnodeconnect`
for syntax and example.

You say `\nodeconnect[t]{x}[b]{y}` if you want to connect
top of node x to bottom of node y.
See `\abarnodeconnect`
for syntax and example.

You say `\nodeconnect[t]{x}[b]{y}{2pt}[3pt]` if you want to
connect top of node x to bottom of node y, with a curve specified by 2pt and
3pt.
See `\abarnodeconnect`
for syntax and example.

You say `\nodeoval{x}` if you want to put an oval around node x.
See `\abarnodeconnect`
for syntax and example.

You say `\nodepoint{x}[4pt][5pt]` if you want to create a node
named x at the current position, with size 4pt and 5pt.
See `\abarnodeconnect`
for syntax and example.

You say `\nodetriangle{x}{y}` if you want to connect nodes x and
y by a triangle.
See `\abarnodeconnect`
for syntax and example.

The `\noexpand` command inhibits expansion. In a case like
`\edef \foo {\noexpand \jobname =\jobname}`,
the command `\foo` will contain `\jobname=AFileName`.
This will typeset as `AFileName=AFileName`.
In a test like `\ifcat\noexpand~0 ...`, the `~` command
is not expanded (the test is false, assuming that the tilde is active,
and the 0 is a normal digit).
On the other hand, `\noexpand\jobname` outside `\edef`
or something like that, produces nothing. And `\noexpand\par`
is the same as `\par`, because the `\par` command
cannot be expanded.

This command is ignored by *Tralics*; in LaTeX it inhibits writing on
auxiliary output files.

The `\nonfrenchspacing` command is ignored.
In LaTeX, this modifies the `\sfcode` value of some punctuation
characters to values greater than 1000.

The `\noindent` command starts a new paragraph.

According to TeX, the only difference between `\indent`
and `\noindent` is that the first command inserts an empty hbox
whose width is `\parindent`. A new paragraph is started only if
TeX is in vertical mode, and the `\everypar` tokens are inserted
in TeX's input. If TeX is in vertical mode and sees a character or something
like that (including the first token of the expansion of
`\leavevmode`) it adds an implicit `\indent`.

In *Tralics*, the value of `\parindent` is ignored, as well
as the `\everypar` tokens. Paragraphs are indented by default, so
that `\noindent` adds an attribute, the other command does nothing.
If the current text is centered, flushed left or flushed right,
no attribute is added. Example

\def\sample{This is some text explaining and showing how text is centered, flushed left or flushed right or indented or not indented. \Env} \def\line{\sample\noindent\sample\indent\sample} \def\Env{Mode is normal}\line \begin{center}\def\Env{Mode is center}\line\end{center} \begin{flushleft}\def\Env{Mode is left}\line\end{flushleft} \begin{flushright}\def\Env{Mode is right}\line\end{flushright}

<p> This is some text explaining and showing how text is centered, flushed left or flushed right or indented or not indented. Mode is normal</p> <p noindent='true'>This is some text explaining and showing how text is centered, flushed left or flushed right or indented or not indented. Mode is normal</p> <p>This is some text explaining and showing how text is centered, flushed left or flushed right or indented or not indented.

Mode is right</p> <p rend='flushed-right'>This is some text explaining and showing how text is centered, flushed left or flushed right or indented or not indented. Mode is right</p>

The `\nointerlineskip` command is ignored. In TeX, it
sets `\prevdepth` dimension to a magic value.

The `\nolimits` command is valid only in math mode.
It describes how indices should be positioned.
In the case of `\mathop a\limits ^b`, the translation is a
`<mover>` element containing a and b, rather than
a `<msup>`. If you forget the `\mathop`,
an error will be signaled by TeX, but *Tralics* simply ignores the
command. There are three flags, `\limits`, `\nolimits`
and `\displaylimits` whose meaning is: use always over, use never
over, use over in display mode only. More than one prefix can be given, the
last one has precedence. A command like `\lim`
has `\mathop` and `\displaylimits` flags,
while `\sin` has `\mathop` and `\nolimits`
flags. It happens that the kernel in `<mover>` can
have a `movablelimits' attribute, case where the effect is the same as
`\displaylimits`; this may confuse *Tralics*, in the case
where the attribute is implicit.

For details see `\mathord`.

\def\A#1{\mathop a #1_b, \mathop a#1^c, \mathop a#1_b^c} $\A{} \A\limits \A\nolimits \A\displaylimits $ \[\A{} \A\limits \A\nolimits \A\displaylimits \]

The variable `\@nomathl` controls translation of
mathematical formulas. The default value is zero, and a MathML
object is constructed. If the variable is positive, all
math-commands translate to themselves; for instance the translation
of `\int_x^{-\infty}` becomes
`\int_x^-\infty`. If the argument is negative,
the translation depends on whether the argument is -2 or -3 or
some other value. Consider the following input:

\def\myvar{\phi} $\int_{-\infty}^\myvar f(x) dx=\mathrm{O}\,\left(\frac{1}\myvar\right)$ $x_{\mbox{{\scriptsize{H\,{\sc i}}}}}$ \begin{equation}\text{a}=\hbox{b}=\mbox{c}\end{equation}

This is the translation in case `\@nomathml=-2`. You can notice
that translation of simple objects like `\phi` is an empty element
of the same name, and that braces (even implicit ones, for instance the
second argument of the fraction) produces a `<arg>` element.

<texmath textype='inline' type='inline'> <int/><subscript><arg>-<infty/></arg></subscript> <superscript><phi/></superscript> f(x) dx=<mathrm/><arg>O</arg> <elt name=','/><left del='('><frac><arg>1</arg><arg><phi/></arg></frac> <right del=')'> </texmath> <texmath textype='inline' type='inline'> x<subscript> <arg> <mbox> <arg> <scriptsize/><arg>H<elt name=','/><arg><sc/>i</arg></arg> </arg> </mbox> </arg> </subscript> </texmath> <texmath id-text='1' id='uid1' textype='equation' type='display'> <text>a</text>=<hbox>b</hbox>=<mbox>c</mbox> </texmath>

Translation of the same example, with `\@nomathml=-1`.
It is a single XML element, containing the TeX source
(after macro-expansion).

<texmath textype='inline' type='inline'> \int _{-\infty }^\phi f(x) dx=\mathrm {O}\,\left(\frac{1}{\phi }\right) </texmath> <texmath textype='inline' type='inline'> x_{\mbox{{\scriptsize {H\,{\sc i}}}}}</texmath> <texmath id-text='1' id='uid1' textype='equation' type='display'> \text{a}=\hbox{b}=\mbox{c} </texmath>

Translation of the same example, with `\@nomathml=-3`.
The translation is a merge of the cases 0 and -1. More precisely, a
`<texmath>` is created, and inserted in the
`<formula>` after the `<math>`.

<formula type='inline'> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mrow> <msubsup> <mo>∫</mo> <mrow><mo>-</mo><mi>∞</mi></mrow> <mi>ϕ</mi> </msubsup> <mi>f</mi> <mrow><mo>(</mo><mi>x</mi><mo>)</mo></mrow> <mi>d</mi><mi>x</mi><mo>=</mo> <mi mathvariant='normal'>O</mi><mspace width='0.166667em'/> <mfenced separators='' open='(' close=')'> <mfrac><mn>1</mn> <mi>ϕ</mi></mfrac> </mfenced> </mrow> </math> <texmath> \int _{-\infty }^\phi f(x) dx=\mathrm {O}\,\left(\frac{1}{\phi }\right) </texmath> </formula> <formula type='inline'> <math xmlns='http://www.w3.org/1998/Math/MathML'> <msub> <mi>x</mi> <mrow><mtext>H</mtext><mspace width='0.166667em'/><mtext>i</mtext></mrow> </msub> </math> <texmath>x_{\mbox{{\scriptsize {H\,{\sc i}}}}}</texmath> </formula> <formula id-text='1' id='uid1' textype='equation' type='display'> <math mode='display' xmlns='http://www.w3.org/1998/Math/MathML'> <mrow><mtext>a</mtext><mo>=</mo><mtext>b</mtext><mo>=</mo><mtext>c</mtext></mrow> </math> <texmath>\text{a}=\hbox{b}=\mbox{c} </texmath> </formula>

If you try to put an attribute pair to the formula or math
expression, the behaviour depends on the switch. If it is -2, the
translation is a `<thismathattribute>`
or `<formulaattribue>` element. In all
other cases, attributes are added to
the `<formula>`, `<math>`
or `<texmath>` elements (this last element
receives both attributes). Example

$\thismathattribute{a}{b}\formulaattribute{c}{d} e$

Here are the translation when the variable is 0, -1, -2 and -3.

<formula type='inline' c='d'> <math xmlns='http://www.w3.org/1998/Math/MathML' a='b'> <mi>e</mi> </math> </formula> <texmath c='d' a='b' textype='inline' type='inline'> e</texmath> <texmath textype='inline' type='inline'> <thismathattribute><arg>a</arg><arg>b</arg></thismathattribute> <formulaattribute><arg>c</arg><arg>d</arg></formulaattribute> e </texmath> <formula type='inline' c='d'> <math xmlns='http://www.w3.org/1998/Math/MathML' a='b'> <mi>e</mi> </math> <texmath c='d' a='b'> e</texmath> </formula>

In the case where `\@nomathml=-3` (see above) Tralics
reads a math formula, expanding all commands; the resulting list is
then converted twice as an XML expression. A font switch
like `\mathrm` is interpreted as
`\mml@font@normal`. A special marker is inserted in the
list, preventing this token to appear in the result. More generally,
what follows `\@nomathswi` appears
only in the `<math>` object, and what
follows `\@nomathswii`
appears only in `<texmath>` object.
This mechanism is used whatever the value of `\@nomathml`.
Example

$a \@nomathswi{xy} b \@nomathswii{zt} c$

Here are the translation when the
variable `\@nomathml` is 0, -1, and -3.

<formula type='inline'> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mrow><mi>a</mi><mrow><mi>x</mi><mi>y</mi></mrow><mi>b</mi><mi>c</mi></mrow> </math> <texmath textype='inline' type='inline'>a b {zt} c</texmath> </formula> <formula type='inline'> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mrow><mi>a</mi><mrow><mi>x</mi><mi>y</mi></mrow><mi>b</mi><mi>c</mi></mrow> </math> <texmath>a b {zt} c</texmath> </formula>

Other example. Assume that you want to create a command
`\varPi` which is the upper case equivalent of `\varpi`.
This command should have the same translation as `\Pi`, but
should be presented as `\varPi` in no-mathm mode. Here is a
possible definition. Note that "what
follows `\@nomathswii`" was a list in the previous
example, and braces are kept in the XML; here is the expansion of
`\noexpand`, thus a control sequence name.

\def\varPi{\@nomathswi\Pi \@nomathswii\noexpand\varPi} $a+\varPi$

Here are the translation when the
variable `\@nomathml` is -3.

<formula type='inline'> <math xmlns='http://www.w3.org/1998/Math/MathML'> <mrow><mi>a</mi><mo>+</mo><mi>Π</mi></mrow> </math> <texmath>a+\varPi </texmath> </formula>

The `\nolinebreak` command takes an optional argument.
It is used to inhibit line break at this position in the paragraph.
This command is ignored in *Tralics*.

The `\nonscript` command is only valid in math mode.
A special item is inserted in the current math list.
After all tokens are converted into MathML fragments, if the following
token is a `<mspace>` it will be removed,
provided that the current style is scriptstyle or scriptscript style.
Example

\def\XX{\nonscript\,} $a\XX b_{c\XX d} a\XX b_{\textstyle c\XX d} $

You can prefix the command `\nonstopmode`
with `\global`. Nothing happens, since batch-mode is the only
interaction mode.

The `\nonumber` command can be used in an
`eqnarray` environment to suppress the equation number for
the current line. In *Tralics*, numbers are associated to the formula,
not individual parts, so that this command does nothing.

This command takes one argument and ignores it.

The `\nopagebreak` command takes an optional argument.
It is used to inhibit page break at this position in the text.
This command is ignored in *Tralics*.

In LaTeX, this sets `\lineskip`,
`\baselineskip` and `\lineskiplimit`
to `\normalXXX` (see description below). Does nothing in *Tralics*.

Set by LaTeX to 12pt, updated whenever the font size changes, unused by *Tralics*.

Set by LaTeX to 1pt, unused by *Tralics*.

Set by LaTeX to 0pt, unused by *Tralics*.

Switches to the default color; see
`\color`.

The `\normalfont` command is a command that selects a font of
normal family, series and shape. That is, roman family, medium series
and upright shape. It is the same as `\rm`.

In LateX, it uses
`\encodingdefault \familydefault \seriesdefault \shapedefault`
but the last three commands are not implemented in *Tralics*.
Remember that the encoding is always Unicode. There is a comment in the LaTeX
source that says: The user interface name for `\reset@font` is
`\normalfont`.

The `\normalsize` command is a command that selects a font of normal size.
For an example of fonts, see `\rm`.

The `\not` command is most often translated by *Tralics* as
`\neg` (this is wrong). But MathML gives no easy way to negate an
operator... There are some hacks: `\not=`is replaced by
`\ne`. This can be wrong in cases like `x_\not=1`.

It can be used as boolean negator inside conditionals defined by
`\ifthenelse`.

It can be used as boolean negator (equivalent to `\not`)
inside conditionals defined by
`\ifthenelse`.

The `\notin` command gives a `not in' symbol:
`<mo>∉</mo>` (Unicode U+2209, ∉).
See also description of the
`\smallint` command.

If you say `\let\foo\@notprerr`, then calling `\foo`
provokes the error *Can be used only in preamble*

You can say `\notrivialmath=93`, this changes the value of an
internal counter
(See scanint for details of argument
scanning). By default, the value is one, unless you call *Tralics* with
the switch trvivialmath or notrivialmath.
The value C of this counter (modulo 8) is considered. If the first
bit of C is set (i.e., if C is odd), then
` $1^e$, X$^{eme}$ $4^{i\grave{e}me}$` is considered a sequence of
trivial math expressions, and translated as
`1<hi rend='sup'>e</hi>`, or
`X<hi rend='sup'>e</hi>`, or
`4<hi rend='sup'>e</hi>`,
that may be rendered as 1^{e}, X^{e}, 4^{e}.
Expressions that match are formed of an optional sequence of digits, a
superscript character, a special exponent; valid exponents are th, rd, rt,
st (for English), or e, ieme, eme, ième, ier, er, iemes, ièmes, es, ère, re
(for French). The exponent can contain font changes like `\small`
or `\rm`. As you can see, in French, there may be some
transformation, because many people using wrong abreviations.

If the second bit of C is set (C is 2, 3, 6, 7 modulo 8) then
`$x$ $1$ $\alpha$ $\pm$` is considered as a set of trivial
math formulas,
translated into `<formula
type='inline'><simplemath><x/simplemath></formula> 1
&alpha ±`.
Note that a formula consisting of a single digit matches two rules. Most, but
not all math symbols, produce a non-math value if they are the only token in
the formula. Character symbols like '+', '*', are not trivial;
exception `$-$` is translated like `\endash`.

If the third bit of C is set (i.e. C is 4, 5, 6, 7 modulo 8), then
`$_{foo}$ $^{2+3}$` is considered as a sequence of trivial
math expressions and translated as
`<hi rend='sub'>foo</hi>
<hi rend='sup'>2+3</hi>`.
Candidates are formulas starting with hat or underscore, followed by a
character, or a list containing only characters. In the case
`$^{eme}$`, this rule is applied before the rule that says that
the translation should be `<hi rend='sup'>e</hi>`.
Font changes are allowed, provided that it is the first token in the list, and
the font is one of it, rm, sf, tt and bf, so that `$_{\bf foo}$` is
the same as `\textsubscript{{\bf foo}}`.

In some examples above, the expression is compiled like
`\textsuperscript` or `\textsubscript`
(see `\rm` for how the change the
translation of font commands).
The default value is 7, and the invocation `tralics -notrivialmath`
sets the flag to 0.

The `\nparallel` command is valid only in math mode. It generates
`<mi>∦</mi>` (Unicode U+2226,
∦).

The `\nprec` command is valid only in math mode. It generates
`<mi>⊀</mi>` (Unicode U+2280,
⊀).

The `\nrightarrow` command is valid only in math mode. It generates
`<mi>↛</mi>` (Unicode U+219B,
↛).

The `\nRightarrow` command is valid only in math mode.
It generates
`<mo>⇏</mo>` (Unicode U+21CF,
⇏).

The `\nsim` command is valid only in math mode. It generates
`<mi>≁</mi>` (Unicode U+2241, ≁).

The `\nsubseteq` command is valid only in math mode. It generates
`<mi>⊈</mi>` (Unicode U+2288,
⊈).

The `\nsucc` command is valid only in math mode. It generates
`<mi>⊁</mi>` (Unicode U+2281,
⊁).

The `\nsupseteq` command is valid only in math mode. It generates
`<mi>⊉</mi>` (Unicode U+2289,
⊉).

The `\ntriangleleft` command is valid only in math mode. It generates
`<mi>⋪</mi>` (Unicode U+22EA,
⋪).

The `\ntrianglelefteq` command is valid only in math mode. It generates
`<mi>⋬</mi>` (Unicode U+22EC, ⋬)

The `\ntrianglelefteqslant` command is valid only in math mode. It generates
`<mi>⋬</mi>` (Unicode U+22EC, ⋬).

The `\ntriangleright` command is valid only in math mode. It generates
`<mi>⋫</mi>` (Unicode
U+22EB, ⋫).

The `\ntrianglerighteq` command is valid only in math mode. It generates
`<mi>⋭</mi>` (Unicode
U+22ED ⋭) .

The `\ntrianglerighteqslant` command is valid only in math mode. It
generates
`<mi>⋭</mi>` (Unicode
U+22ED; ⋭).

The `\nu` command is valid only in math mode. It generates
a Greek letter:
`<mi>ν</mi>` (Unicode U+3BD, ν).
See description of the
`\alpha` command.

Because of the definition `\def\null{\hbox{}}`,
the effect of the `\null` is to put, on the XML tree, an element
that is not visible in the printed output.

The `\nullfont` command is a reference to a font. It can be used
wherever a font is required. However no character is defined in this font,
and all parameters are zero. For instance
`\textfont0=\nullfont` is valid.

When you say `\nulldelimiterspace=5pt`,
then TeX will use 5pt as the width of null delimiters
(for instance `\right.`; also on the left and right of a
normal fraction, because `\over` is the same as
`\overwidthdelims..`).
It is ignored by *Tralics*.

(See *scandimen* for details of argument
scanning).

The `\number` command reads a number (a signed 32bit integer) via the
*scanint* procedure. The expansion of the
command is the list of tokens (characters with `\catcode` 12)
of the decimal expansion of the number. In the example that follows,
the expansion of `\Test` is `2`.

\def\Test-#174{#1} \count3=-27 \expandafter\Test\number\count3 4

After the `\numberedverbatim` command is issued,
lines produced by the `verbatim` environment
are preceded by a line number. This command has no effect on the
`Verbatim` environment.

If you say `\numberwithin{foo}{bar}`
then an error is signaled unless both arguments are counters. The first
counter is dependent on the second one (reset when stepped). Moreover
`\thefoo` is `\thebar.\arabic{foo}`. An optional
argument can be used, it will replace the `\arabic` token. This
command introduced in Version 2.13.1.

As in the case of ε-TeX, *Tralics* provides the notion of
expressions of type
number, dimen, glue or muglue, that can be used whenever a quantity of that
type is needed. Such an expression is read by the scanning mechanism;
basically *scanint*
and friends are used to read a quantity, and `\multiply`
and friends are used to perform operations. The four commands that can be used
are `\numexpr`, `\dimexpr`, `\glueexpr`
and `\muexpr`. They determine a type *t*, the type of the
result, and read an expression, that is followed by an
optional `\relax` (that will be read). When scanning for an
operator or the end of an expression, spaces are discarded. An expression
consists of one or more terms of type *t*, that are added or
subtracted. A term of type *t* consists of an initial factor of type
*t*, multiplied or divided by a numeric (integer) factor. Finally, a
factor is either a quantity of type *t*, or a parenthesized expression.
Example.

\ifdim \dimexpr(2pt-5pt) *\numexpr 3-3*13/5\relax + 34pt/2=32pt \else\bad\fi

Here the `\relax` terminates the `\numexpr`. This is the
trace.
You will see *expr so far* when a term is converted into an expression
(prefix `='), or after an addition or subtraction (prefix `+' or `-').
You will see *term so far* after a multiplication or division (prefix
'*' or '/') or a scaling (prefix backslash). In the case of a*b/c, a 64bit
intermediate product is computed.

[8] \ifdim \dimexpr(2pt-5pt) *\numexpr 3-3*13/5\relax + 34pt/2=32pt +\ifdim1 +scanint for \dimexpr->2 +scandimen for \dimexpr->2.0pt +expr so far for \dimexpr= 2.0pt +scanint for \dimexpr->5 +scandimen for \dimexpr->5.0pt +expr so far for \dimexpr- -3.0pt +scanint for \numexpr->3 +expr so far for \numexpr= 3 +scanint for \numexpr->3 +scanint for \numexpr->13 +scanint for \numexpr->5 +term so far for \numexpr\ 8 +expr so far for \numexpr- -5 +scan for \numexpr= -5 +scanint for \dimexpr->-5 +term so far for \dimexpr* 15.0pt +expr so far for \dimexpr= 15.0pt +scanint for \dimexpr->34 +scandimen for \dimexpr->34.0pt +scanint for \dimexpr->2 +term so far for \dimexpr/ 17.0pt +expr so far for \dimexpr+ 32.0pt +scan for \dimexpr= 32.0pt +scandimen for \ifdim->32.0pt +scanint for \ifdim->32 +scandimen for \ifdim->32.0pt +iftest1 true

Note that `3*13/5` is 8-1/5, and this is rounded to 8. In the case of
`\divide`, the result is truncated. All intermediate expressions are
checked for overflow, which is 2^{31} for an integer, and
2^{30} otherwise (in magnitude). This means that dimensions and
components of glue must be less than 2^{14} in units of pt, mu or fil.

One important point is that these operations do no side effects, hence can be
used inside an `\edef`. If used out of context, you can see error
messages like *You can't use `\numexpr' in horizontal mode*, (the
messages depends on the current mode), in *Tralics*, the error is
*Read only variable \numexpr*, because these operations
are implemented as the value of a read only variable.
Example

\def\foo#1#2{\number#1 \ifnum#1<#2, % \expandafter\foo \expandafter{\number\numexpr#1+1\expandafter}% \expandafter{\number#2\expandafter}% \fi} \edef\Bar{\foo{7}{13}} \def\xBar{7, 8, 9, 10, 11, 12, 13} \ifx\Bar\xBar\else \bad\fi

The `\numero` and `\no`
commands translate the same as
`n\textsuperscript{o}\xspace`.
Before version 2.8.2, it was
`№`, an entity defined by the raweb.

The `\Numero` and `\No`
commands translate the same as
`N\textsuperscript{o}\xspace`.
Before version 2.8.2, it was
`&Numero;`, an entity defined by the raweb.

Thes commands are the negations
of `\vdash, \vDash, \Vdash,\VDash`.
They can be used in math mode only. Translation is
a `<mo>` containing
a `⊭` (U+22AC; ⊬),
`⊭` (Unicode U+22AD, ⊭),
`⊮` (U+22AE, ⊮),
or `⊯` (U+22AF; ⊯)
respectively.

The `\nwarrow` command is valid only in math mode.
It generates an arrow that points North-West:
`<mo>↖</mo>` (Unicode U+2196, ↖).

See description of the \leftarrow command.
